“I Have Sensitive Teeth!”

Do you suspect you have a cavity because you have a sensitive tooth? Do you stay away from ice cream, even though your teeth are not your waist line?

Tooth sensitivity is a common problem. It can be brought on from temperature change, applied pressure or touch;  each sign and symptom tells a different story. There are two types of tooth sensitivity :

Dentinal sensitivity is quite common and is caused when the dentin , the layer of the tooth beneath the enamel , is exposed to your oral environment. As your teeth are used and abused, the outer enamel layer of the teeth becomes worn. Night grinding (bruxism), tooth decay, gum recession and damaged dental work (such as fillings) will all eventually cause the dentin  to become exposed. Because of dentin’s porous nature, when the protective enamel layer of your tooth is compromised, any food or temperature stimulation will affect the nerve endings within the tooth’s core , causing varying levels of pain.

Pulpal sensitivity is an inflammatory reaction of the pulpal tissues, including blood vessels and nerves in the center of the tooth. The causes of this type of sensitivity include tooth decay or infection, recent dental work, night grinding or injured and broken teeth.

To have your dental professional assess your dental condition, you must have a proper diagnosis ! Afterwards, your dentist will provide you with proper treatment options, which could include a proper oral hygiene program, cleaning the mouth after every meal using a soft tooth brush and appropriate toothpaste (containing fluoride or potassium), and brushing and flossing twice a day. Home fluoride rinse or gel can be used to desensitize and remineralize  your teeth. A night guard can be custom fitted to your mouth to protect your oral structure (worn while you sleep). A proper diet (eliminating sweets and/or acidic foods and beverages) will help prevent sensitivity. Your dental professional can work with you to harmonize and balance your bite so all teeth receive proper loading force as well – a proper fit and selection of dental restorations will assure integrity of pulpal health.And there is possibility for root canal therapy or Gum treatments if the problems are more advanced.

It’s time to start taking care of yourself – get the proper treatment for your tooth sensitivity and be worry free!

“How Long Will It Last? Bonding vs. Veneers”

“Does it hurt? How long will it last? How long will it take? How much does it cost?”

These are common questions from patients looking for cosmetic dentistry.

If you’re interested in cosmetic dentistry to get yourself a winning smile, whether the problem is mis-alignment, cracked or chipping teeth, unsightly spacing, uneven or dark colored dentition, uneven or too much (or not enough) smile showing, or even gum erosion, the eternal question always arises: What would be the best solution?

In the past, crowns were the primary choice for masking tooth problems, but since the late 1980s, cosmetic dentistry has offered both bonding and veneers to improve your smile. This leads to the eternal question: “Bonding or veneers?”

Dental bonding involves the application of a durable composite material directly to the surface of the tooth, by your dentist, which is then sculpted and artistically shaped to the exact look the patient desires, to blend naturally and seamlessly with the patient’s existing teeth. A laser (or high intensity light) is then used to cure the composite material, hardening and reinforcing it to the surface of the tooth. This bonding technique has many applications, not only for aesthetic uses but also for prosthodontics and pediatric dentistry. The advantages to dental bonding are a quick treatment time (can be completed in one office visit after a consultation), and a relatively low cost per tooth when compared with porcelain veneers. Durability of bonding will be affected by the oral environment. Since composite bonding is a mixture of quartz particle (70% – 80% filled) and resin, discoloration and breakage is inevitable if your mouth has a high acidic pH value (if you are a soda drinker, lemon lover or candy sucker), if the bonding was not supported by a solid tooth structure, or if you are a night grinder.

Porcelain veneers are fabricated in the laboratory. They are 100% filled with hard mineral particles, and are fired at a high temperature with a vacuum (to procure the best physical properties to sustain the veneer’s strength in the harsh oral environment). Compared to bonding, there is more procedural work involved with porcelain veneers. There are different techniques to fabricate the veneer pieces (which call for different methods of preparation for the tooth); the pressing technique produces a stronger veneer, but requires 0.8mm thickness of the veneer. The porcelain powder build-up technique can produce super thin veneers (0.3mm), which produces a very conservative look on your tooth structure, while at the same time keeping a natural silhouette. The veneer piece lays on top of the tooth structure and is similar to a press-on nail. They chemically adhere to the tooth with bonding composite cement; since porcelain is acid resistant and stronger in physical properties than composite material, this restoration provides long-term service. When getting the veneers, the first visit consists of preparation and imprints f the teeth (which might involve anesthetic ). After this, you will leave the office with temporary veneers which look like natural teeth. A wafer-thin veneer is then crafted out of porcelain which is seamlessly cemented to the front side of the tooth on the second visit. In addition to straightening teeth, porcelain veneers can close gaps between teeth, whiten teeth that do not respond well to bleaching , and can also be used to protect damaged tooth surfaces. The advantages to porcelain veneers over bonding is that veneers are much longer lasting (and stronger) than composite bonding material.

Whether you decide to invest in dental bonding or porcelain veneers, make sure you have all work done at a reputable dentist, preferably at a practice which has its own in-house ceramic lab. When ceramic work is done by an in-house lab with an in-house ceramist, any changes that need to be made to the length or color of the veneers can be done without requiring an additional office visit. Remember, the result of the cosmetic procedures are truly varied depending on the ability of the dentist, ceramist, your clinical situation and the communication between all parties involved. Do your research!

Both bonding and veneers are additive procedures, depending on the position, alignment and shape of your teeth, which is the foundation for any new restorations. This foundation will need to be in the right fundamental situation to receive restorations to result in a fabulous smile. In other words, sometimes, you do not need to do much to your own teeth before applying cosmetic restorations. It might be necessary to reduce or modify the tooth structure before anything can be added onto it to make it look perfect.

There is some risk involved with cosmetic bonding or veneers, so be cautious with any cosmetic procedure. A comprehensive evaluation of your present dental condition is absolutely necessary as a first step; blue prints of your teeth and of your prospective dental project are needed to establish clear verbal communication between all parties involved (including you), including possible mock-up or wax-up models to preview possible changes, which could avoid costly mistakes.

Do your homework: finding the right dental professional, discussing every aspect of your dental needs, understanding the pros and cons of each procedure, and making an educated decision will ensure you get the smile you’ve always wanted.
